Kazakhstan to give up chlorine water purification soon

Kazakhstan will start producing and using new water treatment systems that use carbon filters and ultraviolet light this fall, Tengrinews reports, quotes Sergey Yefremov, an expert in the field, as saying.

Yefremov is the head of composites laboratory at the R&D Center of Physical-and-Chemical Methods of the Al-Farabi University in Almaty. The new method will enable Kazakhstan to abandon the use of chlorine in tap water treatment, he said.

The running tests were initially scheduled for the spring of 2014, however, there were problems in the system that took a whole season to eliminate.

Now the researchers are confident that the test will be successful and are planning to start commercial production of the invention immediately after. The system will most probably be first used in Karaganda water utilities in central Kazakhstan.

The water treatment system employs activated carbon filters on pH neutral (pH 7) base. Filters are paired with UV emitters, which destroy bacteria.
